"I am taking nothing for granted. We may have to. It is getting very tight now."
That's why the Old Trafford boss has one eye on the African Nations Cup in Ghana.
He admits he would love to see a final between the host nation and the Ivory Coast, so that key players from their title rivals are prevented from making a quick return.
Grant is also missing Michael Essien as he is helping Ghana's cause.
Ferguson said: "It is my wish the Ivory Coast and Ghana make the final and keep the players occupied.
"Avram Grant and Arsene Wenger know fine well what I am hoping for. You have to be selfish in a case like this.
"Can you get a replay in the final of the African Nations Cup? That would be good!"
